LQADING- APPARATUS;

Application filed August'29, 1921. Serial No. 496,339.. 2

This. invention is. designed to, store and facilitate the loading of materials. is particularly efi'ective in the handlingof materials for concrete Work such as. concrete roads. With. such work it is. usually desirable to, have the different classes. of material as broken stone, gravel, sand and ce- 'ment and these shouldbe very accurately proportioned. With the present invention this material is measured and delivered at, one operation to a truck or similar conveyanceso that it may be carried to the work without further handling and in proportions andquantity desirable for the position and convenient for handling.

The invention is illustrated in. the accompanyingdrawings as follows Fig l shows a front view of the apparatus. I

1 marks a bin which is. preferably hop.- per=shape and suspended from a frame 2 carried by suitable posts 3. A track formed .of two. railsv 8. extends under the bins to a point in front of the bins. The tracks are carried by the beams 9. supported by the posts 3 and by beams. 10 on front posts 11. The. beams 9 are sufliciently elevated to. permit. a truck or. conveyance 12. to pass under them in position. to be loaded and the posts 11 are sufficiently in front of the front posts 3. to permit of such passage. A transfer car 15 is mounted on the track 8; It is provided with longitudinal sills 16 between which are arranged the wheels 17 on an axle, 18. Cross beams 1 9'extend from thesills 16,. and hopper-bott-Q JLL compartments t, 5 6' and 7 each compartment having a. capacl-t for. one. batch of one material are suspen ed from the beams 19. The compartments areeachf.

supplied with swinging doors 20 which continue the bottoms 2I and are connected with the bottoms by hinges 22. The doors are maintained in closed position by eccentrics or cams 23. These eccentrics are mounted on shafts 24 carried in bearings on a cross beam 25, the cross beam being supported by the hangers 26. Braces 27 extend from the hangers to the bottoms 21. Worm gears 28 on which is mounted roller 47'.

are fixed: on the shafts.v 24 and; worms meshwith thewormgears 28. The worms 29 are. mounted on a shaft 30 and the shaft 30. i journaled inbearings 31 on the hangers 26. Ahand Wheel 32. i-s provided means of .which the shaft 30 may be turned and thus the camsoperatedto release and close the doors 20. i 7 Cables 33. operate over sheaves 34 carried by the frame. and are secured to the carat the front and rear. The cable operates over a drum 35 and the drum: 35 is operated bya crank 36. The cable winds off and onthe drum 35, that is to say, as the front cable is, Wound up: the rear cable isv unwound so that the. car is'moved forward and back.

A closure car 37 is mounted on the track 8. It has the sills 38 bet-ween which the wheels 39 are mounted on axles 40. Cross beams 41. are; mounted on the sills 38 and carry the closure platform or shutter 42. The. closure car is of such a height that when mounted on the tracks-8' and when moved underthe bins 1 the platform will completely close, the bins. tend sufficiently to the rear of the bins to permit the closure car to moveto. the real". of the; bins permitting the transfer car to be brought under the bins for loading.

In order that the closure car may be operatedautomatically with the a hook 43 is secured to. the side of the closure, car and this is. engaged by a latch 44 carried. by thev transfer car. The latch is pivotally mounted on a bracket 45. on the transfer car andhas an arm 46 extending from it- The roller operates along a guide 48 with a cam end 48?. A cam 49 supported by the frame is arranged in the path of the roller 47 and engages the roller to swing the latch 44: out of engagement with the hook 43. The guide 48 and, cam 49 are so positioned that as the transfer car moves forward the closure car is also moved forwardthrough theaction of the book 43. As. the transfer car reaches'a positionbringin the closure car completely under the bins t e roller 47 reaches the cam 49 and this disengages the hook 43 permitting the transfer car to proceed to a position over the truck. On the return movement the cams operate in a reverse manner to swing the hook to open position until the closure car is en aged and then to close the hook so as to lock the two cars together.

transfer car 1 In the general operation of the device the transfer car is moved under the bins, the movement of the. transfer car under the bins removing the closure car and immediately permitting the filling of the transfer car. The compartments of the transfer car are accurately arranged or proportioned to receive exactly the proper amount of mate rial and as they move forward they are carried With the material just level With the top the front edges of the bins holding back and striking off any surplus and the closure car moves under the bins as the transfer car is removed. When the transfer car reaches a loading position over the truck the shaft 30 is operated, releasing all the doors and dumping at one operation all the compartments. I

The truck is ordinarily provided with compartments corresponding to the compartments on the transfer car as the compartments 4 5 6 and '7' and these are separated by the partition plates 13 Which are hinged to the truck at 14. As many bins 1 are used as there are different materials, ordinarily one for sand and one for stone. The truck is brought in position to receive material from the bin Withro'ck and the rock dumped into each of the compartments at, 5 6 and 7 sufficient for a batch in each compartment. The truck is then brought into position opposite the second bin containing the sand and sand sufficient for a batch for each compartment is droppedinto the compartments in the truck. Then the truck reaches the Work the different compartments of the truck are unloaded successively, each compartment carrying a batch.

What I claim as neW is v 1. In a loading apparatus, the combination of an elevated storage bin; a horizontal track extending under the bin and to a point in front of the bin and above a Way; a transfer car on the track, said car having a plurality of compartments; means for dumping all the compartments on the car simultaneously; means for striking off the excess material on the car as the car is moved from under the bin; and means for opening the bin to fill the car and to close the bin.

2. In a loading apparatus, the combination of an elevated storage bin; a horizontal track extending under the bin and to a point in front of the bin and above a Way; a transfer car on the track having compartments; hinged bottoms for said compartments on the car; releasable devices holding the bottoms closed comprising cams and meansyfor actuating the cams; means for striking off the excess material on the car as the car is moved from under the bin; and means for opening the bin to fill the compartments of the car and to close the bin.

3. In a loading apparatus, the combination of an elevated storage bin; a horizontal track extending under the bin and to a point in front of the bin and above a Way; a transfer car: on the track having compartments; hinged bottoms for said compart nrents on the car; releasable devices holding the bottoms closed comprising cams, shafts on which the cams are mounted, Worm gears on the shafts, Worms acting on the gears, and means for actuating the Worms; means for striking off the excess material on the car as the car is moved from under the bin; and means for opening the bin to fill the compartments of the car and to close the bin.

4. In a loading apparatus, the combination of an elevated storage bin; a horizontal track extending under the bin and toa point in front of the bin and above a Way; a transfer car on the track, said car having a plurality of compartments; means for dumping the compartments on the car; means for striking off the excess material on the car as the car is moved from under the bin; and means for openingthe bin to fill the car and to close the bin when the car is removed comprising a closure car having a platform acting as a shutter for the bin the closure car having a connection With the transfer car operating the closure car with the transfer car to close the bin.

5. In a loading apparatus, the combination of an elevated storage bin; a horizon tal track extending under and to a point in front of the bin and above a Way; a transfer car on the track; means for dumping the transfer car; means for striking off the excessmaterial on the car as the car is moved from under the bin; and means for opening the bin to fill the car and to close the bin as the car is removed comprising a closure car having a platform acting as a shutter for the bin, said closure car operating on the same track as the transfer car.

In testimony whereof I have hereunto set my hand.
